Jetting data
Posted: Wed Aug 13, 2014 6:58 am
Thought I'd get a rolling post going about jetting choices. What has worked and what hasn't.
List your bike, applicable modifications and jetting choices you made to accommodate them.
I've got a 380J that's all stock except for fiber pod filters. They have a fairly large surface area and seem to draw a good deal of air. Accordingly I am up 1 size on both pilot and main jets. Needle position is on the middle clip. Bike runs fairly strong in this setup but there is a slight 'rich' hickup around 4500 likely caused by the overlap in pilot and main circuit.
